本文实例讲述了ThinkPHP打开验证码页面显示乱码的解决方法。分享给大家供大家参考。具体分析如下:
在用thinkPHP开发的时候,有时会出现验证码乱码的问题,解决方法是把如下这个文件放在根目录,访问后就可以解决了,具体的PHP代码如下:
function checkdir($basedir){
if ($dh = opendir($basedir)) {
while (($file = readdir($dh)) !== false) {
if ($file != '.' && $file != '..'){
if (!is_dir($basedir."/".$file)) {
echo "filename: $basedir/$file ".checkBOM("$basedir/$file")."
";
}else{
$dirname = $basedir."/".$file;
checkdir($dirname);
}
}
}
closedir($dh);
}
}
function checkBOM ($filename) { global $auto; $contents = file_get_contents($filename); $charset[1] = substr($contents,1); $charset[2] = substr($contents,1,1); $charset[3] = substr($contents,2,1); if (ord($charset[1]) == 239 && ord($charset[2]) == 187 && ord($charset[3]) == 191) { if ($auto == 1) { $rest = substr($contents,3); rewrite ($filename,$rest); return ("BOM found,automatically removed."); } else { return ("BOM found."); } } else return ("BOM Not Found."); } function rewrite ($filename,$data) { $filenum = fopen($filename,"w"); flock($filenum,LOCK_EX); fwrite($filenum,$data); fclose($filenum); } ?>
